Tips:
KSD301 and KI 31 are the same 1/2 inch thermostat, but the way of naming is different, the same type has a well-known manufacturers model 1NT/TK 24/36T /US-118 /T11 and other names. Performance is consistent and all are interchangeable.
Installation Precautions:
1.Before installing this part, unplug the household appliances,Cut off the power completely.
2.Take a picture first before removing any parts, so you know how to restore everything at the end.
3.The temperature controller is a series circuit, not parallel, installation must refer to the original product circuit design.
4.Do not collapse, loosen or deform the top of cover surface during installation to avoid affecting performance.
5. Lock the screw hole, should be fixed at the same time, then lock, avoid the bracket to the other side of the tilt, resulting in temperature control aluminum cover deformation, temperature control parameters change.
6. For the sake of safety, the connecting wire terminal shall be insulated and closed.
7.Do not allow liquid to penetrate into the interior of the thermostat or crack the housing.
8.The thermostat should be stored in a warehouse with RH less than 90% and ambient temperature less than 40 ℃, which is ventilated, clean, dry.
9. CHOKING HAZARD -- Small parts. Not for children under 3 yrs.
